Recently acquired 2240 had over 15 gallons of hydraulic fluid in a 7 1/2 gallon capacity system. With that amount in the system, the brake pedals stayed hard. I drained the system and filled it with Highguard to the correct amount, new filter, and cleaned the sump screen. Since then, there's no brake pedal until you pump it five or six times. Then the brakes are firm and work fine. There are no other hydraulic issues.
Would I be correct in assuming that the check valves key #9 need to be replaced?
